This paper describes the theoretical and practical design studies undertaken to improve the curving perfornrance of the British Rail Class 37 Co–Co locomotive to reduce expensive wheel and rail wear on the West Highland Line. Observatiomfrom preliminary performance trials with a locomotivejitted with prototype steering bogies are also discussed. It is shown how a traditional design can be improved through current theoretical understanding to provide a practical solution to an operating problem.
